Brake Light Switch

I took a look at the pedal box today with a view to fitting the brake light switch. While I was at it I also took the opportunity to "persuade" the pedals in a vice to give me a bit more clearance for my size 9's. The brake light switch mounts on a bracket supplied by GD which bolts onto the face of the pedal box and holds it in position against the brake pedal itself. This gave me an idea for the circuit I'm putting together to control the reverse lockout solenoid. I've posted about it here "click". I'm planning to use a second brake light switch mounted against the clutch pedal to make the reverse lockout circuit "live" when both the brake pedal and clutch pedal are depressed. The theory being you'll only want to put the gearbox into reverse whilst you've got your foot on the brake and the clutch depressed. This also gives me a circuit to control the neutral safety switch which I'm going to wire so the clutch has to be depressed before the engine will start. Hopefully this will help avoid any mishaps which might occur trying to start the engine in gear ! Anyway, I made bracket, the same as the GD one, to hold a second brake light switch for the clutch pedal. Just got to get a second switch now and we should be away!



One area that give's me a little concern is that when placing the brackets on the front face of the pedal box I didn't look to see what clearance I had behind. Where the holes come through doesn't really leave enough room to fit the nut and washer on behind. I had a feeling this might be the case after drilling the pilot holes so I made the final hole a little smaller than needed for the bolts to pass straight through and cut a thread into the pedal box instead. It all bolted up nicely and seems OK I'm just not 100% sure on the strength of cutting a thread into cast aluminium. I guess time will tell!
